Why does jeopardy.app show "You need to enable JavaScript to run this app"?

jeopardy.app is a JavaScript-based web app, so that message means your browser is loading the page but not executing the scripts the app needs. Enable JavaScript for the site (and remove anything blocking scripts), then reload. If the message persists, try an up-to-date browser or a different network.

What the message actually means

The text is a fallback notice, not an error from the game itself. The page's HTML loads, but the app's interface is built by JavaScript at runtime. When scripts are disabled or blocked, there is nothing to render, so the browser shows the fallback line instead of the game.

Common causes, roughly in order of how often they apply:

• JavaScript turned off in browser settings, or blocked for all sites.
• An extension blocking scripts (ad blockers, privacy or "script blocker" tools, some antivirus browser add-ons).
• A content blocker or restrictive browser mode (for example, a hardened privacy mode that disables scripts by default).
• A stale cached copy of the page, or an outdated browser that fails on modern script features.
• A network or corporate filter stripping scripts from the page.

Enable JavaScript in common browsers

The exact menu names vary by version, so treat these as the path to look for rather than a fixed click sequence.

Chrome and Edge (desktop)

1. Open Settings and search for "JavaScript" in the settings search box.
2. Open Privacy and security → Site settings → JavaScript.
3. Set the default to Allowed (or "Sites can use JavaScript").
4. If you use "Don't allow sites to use JavaScript" as a default, add jeopardy.app under the allowed exceptions instead.
5. Reload the page.

Firefox (desktop)

1. Open Settings and search for "JavaScript."
2. Check Privacy & Security → Permissions and confirm JavaScript is enabled.
3. If you use an extension such as NoScript, allow jeopardy.app in that extension.
4. Reload the page.

Safari (macOS)

1. Open Safari → Settings → Security.
2. Confirm Enable JavaScript is checked.
3. Reload the page.

Mobile browsers

On iOS and Android browsers, JavaScript is generally on by default, so a block usually comes from a content blocker, a "reader" or data-saver mode, or a privacy setting. Disable the blocker for this site, or open the site in a standard browser tab rather than an in-app browser.

Verify the fix

After changing settings, do a hard reload so the browser fetches the page fresh rather than reusing a cached copy. If the page now shows the game interface, the cause was script blocking. If it still shows only the fallback message, move to the next section.

If the page stays blank or keeps showing the message

Work through these in order, stopping when the app loads:

1. Turn off script-blocking extensions for this site. Disable ad blockers, privacy extensions, and script blockers one at a time, reloading after each, to identify the culprit.
2. Try a private/incognito window. Extensions are usually disabled there, which isolates whether an add-on is responsible.
3. Update the browser. An outdated browser can fail on modern JavaScript even with scripts enabled.
4. Try a different browser. If it works elsewhere, the problem is in the original browser's settings or extensions.
5. Clear the site's cached data for jeopardy.app and reload.
6. Test another network. A work, school, or public network filter can strip scripts; a mobile hotspot is a quick check.
7. Check whether the site itself is down. If other JavaScript-heavy sites also fail, the issue is on your side; if only this one fails across browsers and networks, the app may be temporarily unavailable.

Quick reference

The site's own description is simply "Play multiplayer Jeopardy online with friends," and the page provides no further troubleshooting guidance, so the steps above are general browser fixes rather than site-specific instructions.
